The OP had done research but as stated in the original post "clear and reliable" information was what was sought. The various search results I read [for InstallIQUpdater -- not for the search mentioned by BOAC] did not appear to me to offer that. Various Companies saying different things and attempting to offer their own products did not strike me to be a source of reliable and accurate information. Furthermore I would not assume that because search information comes as " hit number one " it can be taken to be right.
That is why I politely asked if a ppruner could help. Thank you for your comments BOAC and thank you Bushfiva for your helpful response.
